PAPER-Box-COVERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 550,974, dated December 10, 1895. Application led June 18, 1895. Serial No. 553,174. (Nomodel.)

To @ZZ whom t may concern.-

Beit known that I, HARRY A. INMAN, aciti- Zen of the United States, and a resident of Amsterdam, in the county of Montgomery and State of New. York, have invented certain new and useful Improvements in Paper- Box-Covering Machines, of which the following is a speciication.

lWIy invention relates toimprovements in paper box covering machines; and it consists, generally stated, in combining in the same machine devices for supporting a continuous roll or strip of paper, devices for continuously and automatically applying adhesive material to one side of the strip of paper, devices for automatically adjusting the amount of adhesive material remaining upon the paper, other devices for longitudinally and transversely cutting the strip of paper at such points as to properly adapt the paper to cover boxes or covers thereof of different sizes, and devices for supporting and adjusting .the box or cover blank relative to the end of the machine. These several devices are all of them so arranged and combined that they automatically coact with each other and may be worked by a single operator, who at one and the same operation applies covering-paper both to the top of the cover or bottom of the box, as the case may be, and at the same time on the sides thereof in a continuous manner.

In the drawings hereof, Figure l illustrates an elevation of the machine. Fig. 2 illustrates a plan thereof. Fig. 3 illustrates a detail of the scoring devices, somewhat enlarged. Fig. 4 illustrates a diagrammatical View of a strip of paper as cut by the inachine.

A is the bed of the machine, supported upon legs B. These parts may be ofv any preferred construction.

C C C are four posts located at the corners of the frame A, upon which two lateral bars D D are supported. They project rearwardly, as seenat the right hand, and hangers E E are supported upon the projecting ends, in which a shaft F isj ournaled, which supports a reel G, containing the endless band of paper H.

I isa glue-pan having a heating-.box J, see

Fig. 1,) which may be heated by steam entering at K, or otherwise.

L is a glue-roller revolving in the glue-tank, the lower are of which dips in the adhesive material.

M is a toothed pinion, and N is a gravityacting pawl coacting with it, whereby rotation of the glue-roller backwardly is avoided.

O is a cross-bar having a wire link P on one side of it, which presses against the paper. This bar O is supported upon two pins Q Q, which project upwardly from supports R, adapted to slide on the rods D. S (see Fig. l) is another cross-rod directly beneath the rod O, likewise supported upon the pins Q Q.

T is an adjustable scraper. It comprises a cross-shaft, as shown, and a link U, fastened to it, the whole being adapted to rotate in bearings V V', being turned by a thumb-nut WV, and provided with a set-screw Y, whereby the scraper can be set when once adjusted.

The entire gluing device, as shown, is supported upon brackets Z, Z', and Z2, which are hollowed out on their under sides so as to fit over and slide upon the rods D D.

a a are two blocks adapted to slide upon the bars D D, and to them are pivoted two arms b Z), .which have a soft-metal roller c, pivoted in their upper ends.

d CZ are two springs connecting the upper ends of thearms b with studs e, as shown.

f is a wire, the ends of which are attached to the blocks jj of theV cutter-frame hereinafter to be explained, and upon this wire f are arranged two adjustable guides Zz h, which are adapted to move laterally on the wire f and to .be set by set-screws z' fr'.

jj are two blocks adapted to slide longitudinally upon the bars D D, said blocks being bored, as at g, (see Fig. 3,) for that purpose and to be set in any desired position by set-nuts k k, and these blocks are rigidly fastened together by a series of bars Z Z Z, rmly attached to them, so as to make a rigid frame. m m are two additional rods located somewhat above the rods Z Z Z.

n 'n are two blocks or posts adapted to slide laterally upon the central rod Z and to be set thereon by set-screws o, (see Fig. 3,) and p p are two knives having their cutting-edges presented upwardly and fastened in the up- IOO per ends of the posts n n and so adjusted as to lightly rest upon the cross-rods m m and to be supported by them.

q is another post supported upon the central cross-bar l, which is ordinarily stationary and which normally maintains a fixed position in the medial line of the machine; but in order to secure accuracy in adjustment and lateral movement of it at any desired time I provide it also with a set-nut fr. (See Fig. 3.) lts purpose is to serve as a guide or measuring-point for the adjustment of the guides 7L 7L and certain other parts of themachine, all of which are preferably adjusted from the crossing lines on the top of this post, as seen in Figs. 2 and 3.

s s are two light rods or wires, which cross from side to side of the cutter-frame and serve as supports for the paper when severed at the box or cover, so that it cannot drop upon the machine and adhere to or smear the same with the adhesive material.

t t are vertically-adjustable side plates,

slotted, as at u, and provided with set-nuts upon this hub by a pivotal bearing h', pro-A vided with two set-nuts i" i', so that the degree of oscillation or tip of the box-form. g can be regulated.

j is atreadle-bar provided with a retractile spring 7c.

Z is a rod connecting with a bell-crank lever m', pivoted at n to the side of the frame and pivotally connected at its upper end with a longitudinally-sliding bar o, which engages at p by means of a set-screw q with a stud s, attached to the sliding block (L. (See Fig. 2.) Another rod r connects with the movable blade t of a pair of shears at u'. (See Fig. 2.)

The operation of the apparatus is as follows: An endless roll or strip of paper is placed upon the spool or shaft F G. The end of the paper is thence pulled forwardly between the cross-bars O S, under the link P, over the glue-roller L, through the scraper T U, over the wiref, between the guides h,which are properly adj usted for the purpose beneath the roller c, over the cutters 19 1J, and thence between the blades of the shears to the boxform. The operator putting a box-lol ank upon the box-form g when it is in its forwardlytipped position, as shown in dotted lines in Fig. l, takes hold of the end of the paper and pulls it forwardly until it properly registers with the cover. He then applies his foot to the treadle, whereupon the movable blade of the shears t' is brought down and cross-cuts the paper, and at the same time the rod Z, acting through the bell-crank m and rod o', slides forward the blocks d a, whereupon the roller c slides down the inclined edges of the plates t until the roller comes in contact with the upper edges of the knives p p and the vertical position of the plates tis adjusted to the desired length of longitudinal cut on the paper. lf the box or cover is a deep one, this longitudinal cut will be increased; if shallow, decreased. rlhe roller rolls across the upper edges of the knives until it comes in contact with the reverse or oppositely-inclined surface of the side plates t, and then it rises, leaving the cutters, and soon comes in contact with the edge of the plates w and presses them backwardly, overcoming the stress of the springs s z. When the roller has passed above the edge of the cup-shaped notch or recess in the side pla-tes w, then the springs .z press these plates forwardly and the roller rests in the cup-shaped notch or recess, and upon the return movement these side plates travel with the roller c and cause it to describe an upward arc and not come in contact with the cutters at all, until iinally itis again engaged with the primarily inclined surface of the upper edge of the plates t z, and thereupon, as it continues its upper movement, the plates w w are released and, under the action of the counterpoises fy y, are returned to their normal position., resting against the light springs 5 z, ready for a second operation. The springs d d hold the roller c in close contact with the inclined surface of the plates t t or on the upper edges of the cutters p p, as the case may be, and it will be observed that all of the parts are adapted to longitudinal adjustment, so that the paper will be scored or cut in such manner as to iit any sized box or cover. These adjustments are secured by reason of the fact that the devices which apply the adhesive material are adapted to slide longitudinally upon the bars D D, thus allowing a greater or less amount of coated paper between the said device and the box; also the cutter-frame with the roller c and all its appliances are likewise longitudinally adjustable upon the rods D D, and also the box-form supported upon the rod h is longitudinally adjusted, and it will be further observed that the adjustment may be such that a single piece of paper only will be longitudinally slit and cross-cut, or, if the boxes or covers are small, there may be a plurality of longitudinal slits made in the web before the cross-cut of the shears takes place.

The box-form g', as already stated, is so made as to oscillate or tip upon its pivotal support 71,', so that after the operator has applied the paper to the end of the box or cover which is nearest him, the box-form being tipped, the end or side which is farthest from him may be more conveniently manipulated, and, as shown in the diagrammatical sketch, Fig. et, the end pieces c2 c2 will be bent around the corners of the box or cover iirst, and then IOO IOS

the iiap b2 b2, dac. of each piece will be turned down over the end or side of the box orcover covering the turned-in ends a2 a2, and the adjustment may be such that there will be sufiicient paper to turn in on the inside of the box or cover, if desired.

The scraper T U is an adjustable one, as will be readily understood by inspection of Fig. Q-that is to say, the paper passes between the cross-bar T and the link U, and

webwill be regulated Adjustable Scrapers or.

other forms may be employed, if preferred.

It will be apparent to those who are familiar with this art that modifications may be made in the details of construction ofV the parts of my improved machine and still its essentials be employed. l therefore do not limit myself to such details of construction, although those illustrated and described by me have been found very effective for the purposes stated.
